CAR-ROOF.

Specification of Letters Patent.

Patented Sept. 9, 1919.

To all whom it may concern Be it known that I, FRANK W. \VoLrr, a citizen of the United States, and a resident of the city of Parnassus, in the county of have invented a new and useful Improvement in Gar-Roofs, of which the following is a specification.

This invention relates principall to metal car roofs of the all-steel rivete -up type wherein self-supporting roof sheets extend from side plate to side plate of the car and have their side margins raised, lapped and riveted together forming seams which function as carlines.

()ne of the principal objects of the present invention is to enable the roof sheets to be pressed from a rectangular late, that is, a blank sheet having parallel sides, thus eliminating the expense of shearing the blank to special shape before pressing. Another object is to )roduce a seam construction which will be 0 s1 itable section at the ridge of the car to withtand the vertical roof load at this point and which will gradually change into a broad flat section at the caves to withstand horizontal stresses resulting from the rackin and weaving of the car frame. Another 0 ject is to provide a supporting memher at the caves of the car, which will afford a wide flat bearing and riveting area for the roof sheets in the region of the seam and minimize the stresses in the sheets in the region of the rivets, which secure the vertlcal down-turned eaves ends of the sheet to the side plate. Another object of the supporting member is to take care of any leakage which might occur at the lapped seam flanges where they are turned down over the eaves due to a possible misfit, which is liable to be caused by imperfectly formed parts or by the buckling of the parts when the rivets are drawn up. Another object is to simplify the construction of the roof and to cheapen the cost of manufacturing the same.

The invention consists in an all-metal car roof wherein the roof sheets extend across the car and have their side margins raised, lapped and rivotcd to form hollow seams which function as carlines, the seam being of greatenheight at the ridge than at the caves and being of greater width at the eavesthan at the ridge. The invention further consists \Vestmoreland and State of Pennsylvania,

in the combined supportin and flashing member for the eaves end 0 the seams and 1n the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings, wherein like symbols refer to like parts wherever the occur,

*igure 1 is a plan view of a portion of a car roof embodying my invention, parts being shown broken away to more clearly illustrate the invention;

Fig. 2 is a transverse section through the roof, the section being taken on the line 2-2 in Fig. 1;

Fig. 3 is an enlarged cross-section through the eaves portion of the roof, the section being taken lengthwise of one of the seams on the line 33 in Fig. 1;

Fig. 4 is a cross-section through the eaves portion of the roof, the section being taken between seams on the line 4-4 in Fig. 1;

Fig. 5 is a longitudinal section taken through the roof at the ridge crosswise of a seam on the line 5-5 in Fig. l;

Fi 6 is a cross-section of a seam, the section icing taken midway between the ridge and eaves of the roof on the line 6-6 in Fig. 1; and

Fig. 7 is a longitudinal section through the roof at the eaves, the section being taken through a seam and supporting angle on the line 77 in Fig. 1.

The roof illustrated in the accompanying drawing comprises transversely arranged load-sustaining roof sheets 8, which extend from eaves to caves of the car and have downwardly extending flanges 9 at their eaves ends. The roof sheets are supported on Z-bar side plates 10 which have their web portions disposed horizontally and have their inner flanges uppermost and their outer flanges lowermost. The roof sheets are pressed from a single piece of metal of uniform width and their side margins are raised above the plane ofthe body of the sheet forming outwardly extending horizontal flanges 11, which are connected to the body of the sheet by parallel web portions 12, forming side marginal flanges of substantially inverted L-shaped section. The web portions 12 of the side'marginal flanges of the sheet gradually diminish in height from the ridge toward eachend and the surplus metal, resulting from this tapering of the web, portion 12 by reason of pressing the sheet from a rectangular piece of metal, causes the horizontal flange 11 at each side of the sheet to widen out uniformly as the depth of the web portion decreases until the flange 11 reaches a point adjacent to the eaves end of the sheet where it merges into the plane of the body sheet.

The roof sheets are lapped along their side margins and the raised side marginal flanges 11 are rigidly secured together by means of rivets 13 forming seams of inverted channelshaped section which function as carlines and whose depth decreases from the ridge toward the caves and whose width increases from the ridge toward the eaves.

The widening out of the lapped flanges 11 of the seam, which constitutes the carline, from the ridge toward the eaves allows additional riveting space and permits two rows of the rivets 13 to be used for securing the lapped flanges together. Preferably, the row of rivets which secures the open side of the seam has a greater number of rivets, for the purpose of securing a water tight joint, than the opposite row which secures the marginal edge of the underlapping flange to the overlapping flange of the adjacent sheet, the purpose of this last mentioned row being to render the seam more rigid.

A supporting and flashing member 14 of angular section is located understhe eaves ends of the sheet at their lapped portions and extends a short distance beyond the seam on each side thereof. The vertical flange of each of these angles is located outside of the innermost flange of the Z-bar side plates 10 and is secured thereto, together with the downwardly extending lapped flanges 9 at the ends of the roof sheet, by means of rivets 15, which also secure the eaves flanges 9 of the sheets to the innermost flange of the 2" bar side plates between seams. The other flange of the angle 14 projects inwardly, parallel with the body portion of the sheets, over the upper edge of the innermost flanges of the Z-bar side plates "and the lapped flanges 11 at the side margins of the sheets, together with the adjacent body portion of the sheets at each side thereof, are secured thereto by means of rivets 16. These rivets, which secure the lapped seam flanges 11, are preferably provided with washers 17, which act as spacers and supports for the top of the roof seam and also afford aidin riveting.

The running boards 18 are arranged lengthwise of the car and are securely bolted to the lateral flanges of the channel-shaped metal running-board saddles 19. The running-board saddles 19 rest on and are riveted to the lapped seam flanges -11 by means of the rivets 13 which also secure said flanges together.

With the foregoing described arrange 'ment, it is evident that the lapping and riv- The angle members 14 located under the.

seams at the eaves of the car support the roof sheets and relieve the downturned eaves flanges 9 of the roof sheet, which are riveted to the vertical flanges of the Z-bar side lates 10, of the'greater portion of the weig it of the roof, and also aflord additional means for securing the sheets at the eaves. By reason of the angle members 14 being located directly under the lapped seam flanges 11, with their vertical flanges located outside of the vertical flanges of the Z-bar side plates, a flashing effectis obtained whereby any water, which may enter be tween the lapped seam flanges 11 where they are turned over the eaves due to an imperfect fit, is caused to flow out over the side plate flanges.

The shape of the side marginal flanges of the sheets permits use of all of the metal contained in a sheet hlankof rectangular shape without the expense of trimming the blank to a special shape before pressing.

It is evident that the supporting angle bracket 14 is applicable for use in connection with roots having side plates and seams of various sections; also that the roof itself is applicable to various designs of supporting framing; therefore, I do not wish to be limited to the details of the construction.
